[BioC] read.marrayRaw()

[Julia Engelmann]

Hi list,

I am using the marray package to read in two-color cDNA array data (R 
1.9.1, marray 1.5.14, linux).
When I try:
 >theLayout = new("marrayLayout", maNgr=8, maNgc=4, maNsr=24, maNsc=24)
 >a= read.marrayRaw(files, name.Gf="CH1I", name.Gb= "CH1B", 
name.Rf="CH2I", name.Rb="CH2B", layout=theLayout)
a is a marrayRaw object with only one spot.

When I omit the layout in the read.marrayRaw call and assign it later, 
it seems to work fine:
 >a= read.marrayRaw(files, name.Gf="CH1I", name.Gb= "CH1B", 
name.Rf="CH2I", name.Rb="CH2B")
 > a at maLayout <- theLayout

In my older R version (R 1.9.0, marray 1.5.8) the first call also worked.
Now my question is: Has the read.marrayRaw function changed in some way 
(I haven`t found anything in the documentation), is it a bug or 
something else still?

Any help or information is highly appreciated,
Julia
